2.2. DESCRIPTION
Fibre Optic ADA-7040 is a device used to connect units with RS485/RS422 interface without interfering with the data format. The use
of fibre-optic provides complete isolation between connected devices and resistance to interference on the transmission bus. The fibre
connection is implemented by a line consisting of two fibres - one fiber for the TX signal and one for RX signal. Using two this type
converters, can be use for communication with devices quite distant from each other eg. Computers, controllers etc.
ADA-7040 is equipped with screw terminal block for RS485/422 and power connections. The converter supports data rates of up to
2Mbps by four or two pairs of twisted pair connected to the screw terminals. The device use to operate lines RX +, RX-, TX +, TX-.
To RS485/422 bus built on the ADA-7040 can be connected 32 devices operating in half duplex mode or full duplex mode.
Overvoltage protection was made on base safety diodes and fuses on each RS485/RS422 lines.

3. INSTALLATION
This chapter will show how to connect ADA-7040 to RS485/422 bus, Fibre-Optic and power supply and how to use it.
In the purpose of minimization of disruptions from environment is being recommended to:
● apply multipair type shielded cables, which shield can be connected to the earthing on one end of the cable,
● arrange signal cables in the distance not shorter than 25 cm from powering cables,
● apply cable of adequate cross-section due to voltage drops for converter powering,
● use Interference suppression filters for power supply converters that are installed within a single object.
● not supply converter from power circuit device that generates large impulse interference such as transmitters, contactors,
3.1. ASSEMBLING
The ADA-7040 converter case is adapted to assembly on TS-35 (DIN35) rail. To install converter should mount device on the rail
upper part of the case then press bottom part to hearing characteristic „Click” sound.
3.2. CONNECTION TO RS485/RS422 NETWORK
RS485/RS422 interface at ADA-7040 converter is available on terminal block described as: Tx+/A, Tx-/B, Rx+, Rx-. ADA-7040 support
operating on RS422 bus and RS485. Both buses need proper cabling.

3.2.4. LINE TERMINATION Rt ON RS485/RS422 BUS.
The application of Line Termination (terminator) Rt = 120 W will reduce electrical reflection in data line at high baud rate. It is not
needed below 9600Bd. Should be used the Line Termination resistor if the distance is over 1000m @ 9600Bd or 700m @ 19200Bd
transmission. Example connection of Rt are shown on Fig. 3, 4 & 5. Two resistors Rt =120W , are supplied with ADA-7040 converter,
free of charge.
3.3. CONNECTION FIBRE-OPTIC BUS
The multimode Fibre-Optic with connectors type: ST® , SC or SMA, connect into their corresponding converter's connectors type: ST®
, SC or SMA like on the Fig. 6. Connecting the fiber optic cables should be cautious and careful not to damage them or dirty. If it is
necessary to lay the cable at an angle, must be created the appropriate bends

3.4. POWER SUPPLY CONNECTION
The power supply to the ADA-7040 converter should be DC (regulated) from 10 V= to 30V=. Nominal power is typically 2W, e.g. ZS12/250 or DR-15-24. Power cable from DC power supplies to device must not be longer than 3m.
Observe the polarity, connect positive (+) of DC power supplies to V+ and negative (-) end to V- screw terminal block. ADA-7040 has
the protection from opposite connection power supply. If after power, on the front panel is not lit green LED PWR, check the power
connection (polarity).
